  I don't know exactly what you are asking but surely it is NOT about a "ceiling fan".  A ceiling fan uses electricity to cool a room.  It does not produce or store electricity so CANNOT be used for "power backup".

Maybe a ceiling fan that is battery operated?  You can buy one on Amazon for a few dollars.

You would need to know the power consumed by the motor and the energy capacity (mAh) of the battery. From that you can work out the lifetime of the battery (or, the size of battery needed for a given period of operation).

There isn't really much more that can be said with this little detail.

This could be a failure of google translate. Perhaps the poster is asking about building a roof turbine for generating wind power?

Ah, very good. Sounds more likely.
